Because I would think LOTR would be in an analagous situation with Trek since the Lord of the Rings books have such a history and have a similar set of nit-picking fans.
Not really analogous in any way. LotR films were an adaptation of respective books, so people going into it knew they didn't have to read the book, as the films were based on them. STXI however has 10 films and hundreds of hours of television, not to mention books and comics preceding it, and potential newcomers might be unsure as to weather they need to see any of that or not to understand it.
